My invention relates to improvements in washing machines, and the objt oat einvention -is to devise means for provi contain water p from the centre of they machine tof the periphery and for a free return of the water from the periphery to. the centre said circulation being perfonned mpiely kwithin the body of th machine, thereby dispensing with the use of return pipes, and it consists essentiallyv of the arrangement and construction of arts hereinafter more particularl descri Fig. 1 is a sectional view ugh my ma- Fig. 2 is a plan view, the partsy thereof bebroken away in section to exhibit the interior structure thereof.

In the drawings like characters of referencel indicate corresponding parts in each 1 indicates the lpdy or main container of my w machine provided with a cenashing un tral opening 2 in the bottom wall thereof.

10 is an inner container the bottom plate of which in proximit -to its outer cperipheraLedge i's 'suppe in the notche recess 9". 'The wall of the inner container 10 pref.- erably ares outward, as indicated at 10" and extends upwardly at least as high as the the upwardly extending parts o the. vanes 9.

11 is an orifice formed in the centre of the inner container 10 around which extends an annular flange 12 forming an annular water containing space 13 extending between the wall 12 and the bearing member 4.

The inner container 10 is supported in a stationary position upon the walls 9, and therefore forms `a stationary unit with the main container 1.

. 14 is a revolving water container conforming in sha .tothe inner container 10,- but of smaller iameter, and fitting therein to form a water containing interspace` 15 'between theside walls of the inner container 10 and revolving container 14 and also be'- theupwardly extending annular vwall 12 of theinner container 10 extends.

17 4is a cylindrical member extending upward from the orifice 1.6 and provided with a'closed u per end 17* havin a centralbose 18 provi ed with a centra orifice 19 in which is secured 'the lu per end of the main e wall of the c linora-y shaft 3 by a pin 20. Y drical rtion 17 is provided with. tions 17,3 The upper of the wa out-turned horizontal annular lip 21, the in edge portion 22 being referably convexed to'permit of the free ow of water thereover. n

The lip 21 extends over the upper edge of the inner container wall 10 in close proxmity -tween the bottomV of the container 10 andl 1 of the revolving container 14 1s provided with an 23 and 24 are annular members, the walls of which are inclined to correspond with the incline of the wall of the container 14.

25 are ribs secured to the exterior of each member 23 and 24, the outer face of vthe ribs having inward inclination correspondin to the inclined. inner surface of the container 14 sc that when the member 23 is set within the revolving container 14, the ribs lit the inneiieri hery of the container 14 and tend to w ge ownward so as to hold the meniber from rotating within such rotating conkiller;

Similarly the rib 25 of the member 24 fits within the member 23 so as to prevent its revolving within such member. It will also be noted that the member 24 is of less depth than the member 23 for a purpose which will hereinafter appear.

Althou h I have shown two of these menibersit wi of course be understood that any number may be employed. t

26v is a discharge orifice provided with a plug 27 b means of whichfthe water is discharged rom the revolving container.

28 is a discharge pipe provided wit-h a valve 29 for 'discharging the water from the main container 1.

Having described the rincipal parts of my invention I will brie y describe the op eration of the same.

The clothes are inserted within the washing machine between the perforated wall of aided by the cylindrical member 17 and the wall of the inner member 24, the clothes sinking down on to the bottom of 'the rrotating water container 14. Water is fed by suitable means into the main container 1, the water passing upward and seeking its own level within the inner container 10 and rotating container 414. The shaft 3 is then driven by suitable means, rotating the container 14 with the clothes therein exert-ing a centrifugal action upon the water, causing it to pass upward over the vconvexed edge 22 and li 21 into the main container, such water ein replaced by water from the main container rising upward through the orifice 11 into the cylindrical lmember 17 and through the perforations into the revolving container. y

The centrifugal actionvthus exerted is also meansof the members 23 and" 24 and theirr inclined ribs 25' which engage'the bo'dy of water within lthe revolving c ontainer 14 and serve to' aid in throwing thel water upward and over the lip' 21'.

By makin the inner member 24 'of less depth than '51e outer member 23 the water in the lower portion of the revolving container engages the Aouter wall thereof, passing up the inclined vwall so as to be engaged y -bv the outer inclined ribs 25 and" thus be thrown upward over the lip 211 The water within the'revolving container 14 above the level of the loweredge of the member 23 is brought into contact as it is vcarried out by centrifugal action with the lower portion of such wall, and is therefore carried up through the interspaee between said wall and the wall otl the member 24,' its movement being aided by the ribs 2,5 loczitedbetween these walls.

It will lthus be seen that a complete circulation is formed, the water passing upward and outward from the revolving container and from tlie clothes over the lip 21 into the outer portion of the main container, gradually circulating downward between the wall ofthe main container and the wall of the inner container l0 and returning between the bottom of the main container and the bottom of the inner container 10 so as to pass upward through the orifice 11 and through the perforations 170 of the cylindrical member 17 back into the revolving container I4 and into the ,body of the clothes contained therein.

The fiow of the water between the walls and bottoms of the inner -and 'outward' fixed containers iszmateriallyiiided by the walls or vanes 9v which serve to prevent rotary motion of the water and utilize its `energy in a downward `and then radial and inward direction. y

I find in practice that it is of 'in'ipoitanee to separate the iniiowing water at the bottom of the outer container from the bottom of the rotating container by means of the "fixed bottom of tlieso-called container 10,

as this infiowing water exerts considerable upward pressure which it 1s not desirable to have actlng directly on the bottom of the revolving container.

It is also important that the -meanseiir ployed to form with .the outer container the' return assages for the water should have an upwardly extending wall as downward and inward flow of water directly incontact with the under side `of the revolving -container is thus in main prevented. l

It is further important that the varies should extend upwardly between the wall of the so-called inner container and the wall of"v the outer container so as to eheck'rotaryv movement and start the waterv lin a downward course with a minimum of eddying, as etliciency of operation with 'a 'minimum of power depends on cutting down frictional losses" in the water'lcirculations as niu'ch as possible.'v Y* f From this description it" will .ber seen that I have devised a very simpl'e'formof wash- 5 ingmachine invwhich' a very -eilieient circulation is provided'for the'wateigboth inanV inward and outward direction whereby thel use of return pipes is dispensed with.l
